Are double pumps equipped with intermediate plate with valves, that are used in applications where is desired an economy of the drive energy and where high pressure is needed only in the final stage of the application. Up to a pressure (less than the switching pressure) the pumps supply together and after this a step supply to the pump inlet and the other in the system until the desired pressure. The commutation pressure is preadjusted. Those pumps are used in equipping elevating platforms, hydraulic presses, a.s.o.
